WASHINGTON (WUSA) -- Starting tonight, the Capitals will face off in the playoffs against the New york Rangers for the fourth time in 5 years. These series are historically low-scoring, and nail-biting. In 19 games, 13 of them were determined by just one goal. So we decided to take a look back at some of the most memorable playoff moments between these two teams over the last four years.

We begin with number five, and we go back to 2009. The Caps trailed the Rangers three games to one, but Washington would rally to tie the series scoring nine goals on Henrik Lundqvist in two games to force a seventh and deciding game.

At number four, Capitals fans heckled Rangers head coach John Tortorella in Game Five of the 2009 series. The fans egged the coach on, and Tortorella responded in a way that got him suspended by the NHL for Game Six.

At number 3, we have the debate in 2011, about if Verizon Center was louder than Madison Square Garden.

The debate began when then Caps head coach Bruce Boudreau said, "Our building is a lot louder... They can say what they want, but it's not that loud there."

While which arena was louder was very debatable, what was not was who was the better team. The Caps were the superior team, winning the series in five games.

At number two, Game 4 of the 2011 series. The Caps were up two games to one, but down 3-0 in the third period. But they would rally with three goals in the third to tie the game. In double overtime, Jason Chimera scored the game winner to give the Caps a commanding lead in the series.

Which leaves up with the most memorable moment. Who could forget April 28, 2009, Game 7 Caps-Rangers? Sergei Federov, in his last NHL season, scores the game winner as the Capitals won their first playoff series since 1998
